Eat larger meals?
Honestly, with your activity level, it sounds like you need to be eating more not less. How about fresh fruit (more water content) rather than dried? Big hearty breakfasts? An extra complete meal during your peak snacking time?
Your body might be telling you it needs more food, and your brain might be derailling that signal into snack food rather than "real" food.
5'7" and 145-150 sounds perfectly normal for someone with muscles to me. Can you actually grab onto a handfull of fat that you'd rather lose? I'm 5'8" and was 145-150, until the off season when I gained 15 lbs. I can grab rolls of fat at my waist and hips. I trust those will melt away as I get into the swing of training for my triathlon again and I add an extra meal (around 3 pm) each day. (during active season I eat 4 meals and 2 snacks a day)
